Component Description

Component	Function
Pre-crash seat belt control unit (driver side)	Integrated front seat belt pre-tensioner, control unit and seat belt motor. Controls pre-crash seat belt control unit (passenger side) as slave control unit. Seat belt motor operates when belt is extended and retracted.
Pre-crash seat belt control unit (passenger side)	Integrated front seat belt pre-tensioner, control unit and seat belt motor. Is controlled by pre-crash seat belt control unit (driver side) as master control unit. Seat belt motor operates when belt is extended and retracted.
Brake pedal stroke sensor	Varies voltage based on brake pedal position and sends the signal to pre-crash seat belt control unit (driver side). There are 2 signals sent from the brake pedal stroke sensor (brake pedal stroke sensor signal 1 and 2). Pre-crash seat belt control unit (driver side) judges the stroke distance and speed of the brake pedal based on the voltage signals sent by each side of the sensor.
Seat Belt Buckle Switch LH	Fastening of seat belt is judged. This signal is used for control of driver pre-crash seat belt system.
Seat Belt Buckle Switch RH	Fastening of seat belt is judged. This signal is used for control of passenger pre-crash seat belt system.
BCM	The following signals are received from the BCM via CAN communication: ignition ON signal sleep/wake signal door switch signal
Air bag diagnosis sensor unit	The following signals are received from the air bag diagnosis sensor unit via CAN communication: pre-rollover signal collision signal
ABS Actuator And Electric Unit (Control Unit)	ABS operation signal is received from ABS actuator and electric unit (control unit) via CAN communication.
ADAS Control Unit	Forward Emergency Braking operation signal is received from ADAS control unit via CAN communication.
Combination Meter	Vehicle speed signal is received from the combination meter via CAN communication.
Steering Angle Sensor	The following signals are received from the Steering Angle Sensor via CAN communication: Steering Angle Sensor signal Steering Angle Sensor speed signal Steering Angle Sensor neutral position adjustment completion signal Steering Angle Sensor malfunction signal
